Japanese Patent JP4177947

Kind Code:

B2

Abstract:

An electromagnetically driving part for use in opening/closing a valve or the like, comprises a guide cylinder (17) in which a movable core (18) is received slidably, and a fixed core (15) fixed to the guide cylinder (17). The fixed core (15) and the guide cylinder (17) are coupled with each other by welding in a state that the guide cylinder (17) is press-fitted onto the fixed core (15). An air gap (16a) is formed between an outer circumferential surface of the fixed core (15) and an inner circumferential surface of the guide cylinder (17). The fixed core (15) and the guide cylinder (17) are welded with each other in a portion where the air gap (16a) is formed. Accordingly, it is possible to weld a guide cylinder and a fixed core with each other surely, and to miniaturize an electromagnetically driving part.
